Abstract
Organic‐inorganic hybrid multifunctional materials have shown significant application in lighting and sensor fields, owing to their prominent performance and diversity structures. Herein, we synthesized two multifunctional compounds: (propyl‐quinuclidone)2CdBr4 (1) and (F‐butyl‐quinuclidone)2CdBr4 (2). By introducing light‐emitting organic cation with flexible long chain, 1 and 2 exhibit excellent transition properties and bright blue‐white fluorescence. Then, combine fluorescence lifetime and first‐principal calculation, providing evidence for the electron transfer emission. Subsequently, investigated the impact of substituent carbon chain length (methyl to butyl), structural rigidity (C−C to C−F) and halide framework (Cl to I) on the fluorescence properties. Results indicate that Cd⋅⋅⋅Cd distance and structural rigidity play an important role in fluorescence. Overall, our research provides valuable insight and example for chemical modifications enhance compound performance. [ABSTRACT FROM AUTHOR]
