Abstract ：
As an emerging class of hybrid complexes, donor-acceptor (D-A) hybrid heterostructures, which combine the advantages of both organic and inorganic photoactive components, provide excellent platforms for the fabrication of photochromic materials with enhanced photo-responsive performances. Herein, four novel hybrid heterostructures, namely H3TPT(PW12O40)2NMP (1), (H1.5TPT)(2)(PW12O40) (2), (H3TPT)(2)(SiW12O40)2Cl2MeCN (3), and H3TPT(HPMo12O40)Cl3NMP (4) (TPT is tri(4-pyridyl)-s-triazine, NMP is N-methylpyrrolidone), have been synthesized and characterized. Benefitting from the strong interactions (anion-pi interactions) and matching electron energy levels between the donors and acceptors, some of them exhibited ultrafast photochromic behaviour even up to 1 second. Furthermore, based on experimental and theoretical calculations, the plausible PIET process and structure-activity relationship have been discussed in detail.

Abstract ：
The development of high-quality organic scintillators encounters challenges primarily associated with the weak X-ray absorption ability resulting from the presence of low atomic number elements. An effective strategy involves the incorporation of halogen-containing molecules into the system through co-crystal engineering. Herein, we synthesized a highly fluorescent dye, 2,5-di(4-pyridyl)thiazolo[5,4-d]thiazole (Py2TTz), with a fluorescence quantum yield of 12.09%. Subsequently, Py2TTz was co-crystallized with 1,4-diiodotetrafluorobenzene (I2F4B) and 1,3,5-trifluoro-2,4,6-triiodobenzene (I3F3B) obtaining Py2TTz-I2F4 and Py2TTz-I3F3. Among them, Py2TTz-I2F4 exhibited exceptional scintillation properties, including an ultrafast decay time (1.426 ns), a significant radiation luminescence intensity (146% higher than Bi3Ge4O12), and a low detection limit (70.49 nGy s-1), equivalent to 1/78th of the detection limit for medical applications (5.5 mu Gy s-1). This outstanding scintillation performance can be attributed to the formation of halogen-bonding between I2F4B and Py2TTz. Theoretical calculations and single-crystal structures demonstrate the formation of halogen-bond-induced rather than pi-pi-induced charge-transfer cocrystals, which not only enhances the X-ray absorption ability and material conductivity under X-ray exposure, but also constrains molecular vibration and rotation, and thereby reducing non-radiative transition rate and sharply increasing its fluorescence quantum yields. Based on this, the flexible X-ray film prepared based on Py2TTz-I2F4 achieved an ultrahigh spatial resolution of 26.8 lp per mm, underscoring the superiority of this strategy in developing high-performance organic scintillators. Two organic halogen co-crystal scintillators with strong halogen-bond-induced charge-transfer interactions enable a fast response, low detection limit and ultra-high-resolution imaging.

Abstract ：
Controlling the aggregation of small-molecule acceptors (SMAs) is essential to obtain an optimal morphology and to improve the photovoltaic performance of polymer solar cells (PSCs). However, reducing intermolecular aggregation of SMAs is usually accompanied by the disruption of compact molecular packing thereby leading to their decreased electron mobilities. Here, two novel M-series SMAs (MD1T and MD2T) based on ladder-type heterononacenes with neighboring side-chains separated by one or two thiophene rings are designed and synthesized. It is found that shortening the spacing of the neighboring side-chains of the SMAs can greatly alleviate the intermolecular aggregation and alter the molecular orientation from bimodal edge-on/face-on to predominant face-on while maintaining the compact molecular packing. As a result, a more favorable morphology with smaller domain sizes is formed for the MD1T-based blend films, which greatly improves the charge generation and charge transport for the corresponding PSCs. The best-performing MD1T-based device affords an efficiency of 12.43%, over seven times higher than that of the MD2T-based device. This work reveals the importance of the spacing between the neighboring side-chains in modulating the molecular aggregation and active layer morphology, and the obtained structure-performance relationships shall provide important guidance for designing highly efficient SMAs.

Abstract ：
The development of novel building blocks with sp(3)-hybridized-carbon-free conjugated skeletons is important to further advance and enrich nonfullerene acceptors (NFAs), but this remains a challenge due to the lack of strategies to effectively modulate the aggregation behavior of resulting NFAs. Herein, two novel nitrogen-bridged octacyclic ladder-type heteroarenes end-capped with thiophene rings (BTPS) or selenophene rings (BTPSe) are designed and synthesized as the donor cores for constructing NFAs (MQX-2 and MQX-4). It is found that replacing the sulfur atoms (MQX-2) at the outer positions of the heteroarene core with selenium atoms (MQX-4) can effectively modulate the molecular packing mode of the NFAs. The incorporation of selenium atoms induces stronger O...Se noncovalent interaction than O...S, thus promoting the formation of mixed H/J-type aggregates in MQX-4. Benefiting from more electron hopping channels, MQX-4 exhibits higher electron transport (more than 1-fold enhancement) and photovoltaic properties compared to MQX-2, which forms only H-type aggregates.

Abstract ：
Low-dimensional inorganic-organic hybrid perovskiteswithhigh moisture tolerance and long-lived charge separation states havecaptured significant attention in the field of optoelectronic devices.To further achieve the relationship between crystal structures andstability, as well as charge separation behaviors, three one-dimensionalhybrid perovskites containing electron-deficient naphthalene diimideammonium (NDIEA) and electron-rich iodoplumbate chains, [(H(2)NDIEA)Pb2I6]center dot 2DMF (1), [(H(2)NDIEA)(2)Pb5I14 center dot(DMF)(2)]center dot 4DMF (2), and [(HNDIEA)(2)Pb2I6]center dot 3H(2)O (3), weresynthesized. Crystal structure determinations revealed various synthesisconditions leading to different stacking modes, especially the inorganiclead iodide fraction, which resulted in different water resistancesand charge-separated behaviors. The comprehensive analysis found thatstrong intermolecular interactions (anion-pi interactionsand pi-pi interactions), and matching energy levelsbetween protonated NDIEA and iodoplumbate chains, can facilitate thegeneration of long-lived charge separation states and extraordinarymoisture stability, even in the water environment. In addition, theconductivity behavior of 3 was also explored in detail. Low-dimensional inorganic-organichybrid perovskitescontaining electron-deficient naphthalene diimide ammoniums and electron-richiodoplumbate chains have been reported, which possess long-lived chargeseparation states and extraordinary moisture stability.
