hyperpolarizability values enabled structure–property studies; these revealed some important structural features that affected the efficiency of intramolecular charge-transfer and nonlinearoptical properties in this class ofheterocyclic push–pullchromophores. The charge-transfer transition was most significantly affected by structuralfeatures such as π-linker length, chromophore planarity, and the number
