Three new naphthaline-type chromophores end-capped with different (p-substituted amino) styryl groups on the both sides (named as BPASN, BHMASN and BMASN) have been synthesized. Under excitation of 380 nm, strong green light-emitting locating at 517 nm with the fluorescence quantum yield of 0.88 in CH2Cl2 has been obtained. In the presence of β-cyclodextrin (β-CD), strong blue-emitting at 456 nm in DMF was also recorded.
