Abstract ：
核磁共振技术(NMR)是迄今为止研究最完全、应用范围最广的波谱技术之一,遍及生物、医药、矿物勘探、化学等领域,多位杰出科学家因为NMR研究而获得诺贝尔奖,其中虞福春和他的同事普洛科特(W.G.Proctor)发现了核所处的化学环境会影响核的化学位移这一现象,也被称呼为Proctor-Yu(虞)效应.紧接着虞福春又在KSbF6的水溶液发现SbF-6的核磁共振谱线存在谱线劈裂现象,最终确认其是由于自旋耦合而产生.而这些重大成果在国内外教科书中鲜少提及.简述了虞福春的成长经历及其对于核磁共振发展的重大贡献.

Abstract ：
Phenanthrenone 1 was synthesized via cyclization of 4,5-dibromo-9-fluorenone with diarylacetylenes, followed by selective reduction of the carbonyl group to yield hydroxyl derivative 2 and methylene derivative 3, alongside reference molecule 4. UV-vis absorption spectroscopy revealed that compound 3 exhibits a blueshift (lambda max = 257 nm) compared to compound 1 (lambda max = 264 nm) due to the disruption of conjugation by the methylene group, while compound 2 (lambda max = 267 nm) shows a redshift compared to compound 3, attributed to the electron-donating effect of the hydroxyl group. Single-molecule conductance measurements using the STM-BJ technique demonstrated a 2-fold difference between 1 (10-4.37 +/- 0.01G0) and 3 (10-4.67 +/- 0.01G0), attributed to the carbonyl group's ability to lower the HOMO-LUMO gap and enhance charge transport. Notably, cyclization at the 4,5-positions has a limited impact on conductance, as evidenced by the small differences between 1 (10-4.37 +/- 0.01G0), 2 (10-4.63 +/- 0.01G0), and 4 (10-4.50 +/- 0.01G0). These results indicate that functional group modifications and skeletal cyclization both influence the electronic properties of phenanthrenone derivatives, with functional group modifications playing a more noticeable role in modulating conductance. This work provides a framework for designing functional organic molecules with tailored electronic properties, advancing the development of next-generation nanoscale electronic devices.

Abstract ：
As an important it-conjugated bridge, (E)-2-styrylthiophene possesses excellent electronic transport and optical properties, showing great potential in nonlinear optical (NLO) applications. In order to investigate the influence of different donor units on (E)-2-styrylthiophene in NLO, we synthesized three thiophene-based D-it-A conjugates with dicyanoacetylene as the acceptor and different donors (MS, PS, FS) by inducing intramolecular charge transfer (ICT). Their third-order nonlinear absorption was studied using Z-scan experiments and transient absorption spectroscopy. Due to the significant ICT, MS exhibited the highest nonlinear absorption coefficient (beta = 1.5 x 10-9 m W-1) and effective third order refractive index (n2 = -12 x 10-17 m2 W-1). Taking the strongest performing MS molecule as an example, we analyzed four types of conjugated bridges through theoretical calculations, which indicated that (E)-2-styrylthiophene has the strongest dipole moment difference (Delta mu = 34.73 D). Finally, transient absorption (TA) spectroscopy revealed that the nonlinear absorption of these molecules is primarily caused by reverse saturable absorption (RSA).

Abstract ：
Organic nonlinear optical (NLO) materials with strong light-responsive properties have garnered significant attention in the field of optoelectronics due to their chemical tunability and cost-effective synthesis. Enhancing the NLO performance of these materials is essential to meet the growing demands in applications such as optical modulation and communication. Interestingly, twisted structures have been shown to alter NLO properties, offering a novel design approach. This review systematically examines recent advances in twisted D-pi-A type organic chromophores for enhancing NLO performance, with a particular focus on the key mechanisms of molecular structure design and performance optimization. It provides a detailed discussion of the design strategies aimed at improving the NLO performance of twisted organic chromophores, highlighting the significance of twisted structures and electronic group design. The literature review indicates that optimizing twist angles, strengthening donor and acceptor group intensities, and optimizing pi-conjugated bridges are effective ways to enhance NLO performance.

Abstract ：
This study presents the design, synthesis, and comprehensive characterization of a novel series of D-pi-A type malononitrile-derived chromophores, BTC-1-BTC-4. Combining various spectroscopic techniques, nonlinear Z-scan measurements, and quantum chemical calculations, we revealed the intricate relationship between nonlinear optical properties and the interplay of molecular structure, intramolecular charge transfer (ICT), and dipole moments (mu). Our experimental and computational findings corroborate that the polarization degree in the ground state, the charge separation in the excited state and twisted intramolecular charge transfer (TICT) collectively dictate the nonlinear optical properties of the compounds. Notably, BTC-1 exhibits an exceptional nonlinear absorption coefficient beta value (2x10(-8) m W-1), attributed to its optimized charge transfer efficiency and pronounced degree of charge separation. Our findings provide actionable insights for the rational design of high-performance organic Nonlinear optics (NLO) materials with potential applications in advanced photonic devices.

Abstract ：
Efficient control over several possible reaction pathways of free radicals is the chemical basis of their highly selective transformations. Among various competing reaction pathways, sulfonimidyl radicals generated from the electrolysis of 2-alkynylbenzenesulfonamides undergo cascade migratory or ortho-cyclization cyclization selectively. It is found that the incorporation of an extra 2-methyl substituent biases the selective migration of the acyl- over vinyl-linker of the key spirocyclic cation intermediate and thus serves as an enabling handle to achieve the synthetically interesting yet under-investigated cascade migratory cyclization of spirocyclic cations.
