Artificial　photonic　synapses,　owing　to　their　high　sensitivity,　low　power　consumption,　and　integration　of　sensing　and　memory,　have　aroused　comprehensive　discussion　and　have　been　developed　into　devices　used　as　the　new　sensors　for　the　Internet　of　Things　(IoT)　and　artificial　neural　networks　(ANNs).　Colossal　energy　consumption　may　be　one　of　the　factors　hindering　the　development　of　neuromorphic　computing.　Herein,　ternary　component　organic　array　films　of　TIPS-pentacene,　polystyrene,　and　CsPbBr3　perovskite　quantum　dots　(QDs)　are　effectively　developed　to　fabricate　photonic　synaptic　transistors.　The　patterned　organic　thin　films　prepared　by　the　solution　processes　can　be　distinctly　controlled　in　the　crystallographic　orientation　using　a　pre-patterned-guided　crystallizing　strategy　and　the　corresponding　transistor　of　TIPS-pentacene　with　mobility　over　1　cm(2)　V-1　s(-1)　is　successfully　achieved.　On　this　basis,　the　ternary　composite　film　exhibits　synaptic　behaviours　from　short-term　plasticity　(STP)　to　long-term　plasticity　(LTP),　including　paired-pulse　facilitation　(PPF),　spike-time-dependent　plasticity　(STDP),　spike-number-dependent　plasticity　(SNDP),　spike-frequency　dependent　plasticity　(SFDP)　and　light-potentiation/electric-depression.　Benefiting　from　the　improved　material　compatibility　and　film-forming　properties　of　small　molecule　semiconductors　and　perovskite　QDs　with　polymer　polystyrene,　our　synapses　still　exhibit　prominent　synaptic　features　at　a　low　power　consumption　of　0.036　fJ.　Utilizing　time-dependent　plasticity,　the　synaptic　device　stimulated　by　a　series　of　light　signals　realizes　wireless　optical　communication.　In　addition,　the　pattern　recognition　function　by　ANNs　is　verified.　This　work　provides　a　feasible　fabricating　path　to　patterned　array　film-based　photonic　synapses　for　the　next　generation　human-computer　interaction　sensors.
