triphenylene-arylisocyanides TPh(OC12H25)5(O(CH2)6OC6H4(NC)-p) (LD1) and TPh(OC12H25)5(O(CH2)6OC6H2Me2(NC)-p) (LD2), have been prepared and their self-assembly, aggregation, optical, redox, mesogenic and conducting properties investigated. Intermolecular π–π stacking, RhI⋯RhI, and RhI⋯AuI interactions rule the crystal packing and aggregation in solution for the complexes with LA, LB, and LC. For the RhI complexes
Rh I络合物 [Rh( L ) 4 ](A) (A − = Cl − , BF 4 − , [Au(CN) 2 ] − ) 与常规芳基异氰化物 ( p -MeC 6 H 4 (NC), L A ; p -MeOC 6 H 4 (NC), L B ; 3,5-(OMe) 2 C 6 H 3 (NC), L C ) 或与烷氧基官能化的苯并芳基异氰化物 TPh(OC 12 H 25) 5 (O(CH 2 ) 6 OC 6 H 4 (NC)- p ) ( L D1 ) 和 TPh(OC 12 H 25 ) 5 (O(CH 2 ) 6 OC 6 H 2 Me 2 (NC)- p ) ( L D2 ), 并研究了它们的自组装、聚集、光学、氧化还原、介晶和导电性能。分子间 π–π 堆积,Rh I ⋯Rh I和 Rh I ⋯Au I对于具有L A、L B和L C的配合物,相互作用决定了晶体在溶液中的堆积和聚集。对于
