A new class of rhodamine luminophores, 3′, 3 ″-bis (oxospiroisobenzofuran)-3, 7-bis (dialkylamino) benzopyrano-xanthene derivatives (ABPX), have been successfully developed. The emission behavior of ABPX series is directly opposite to the concentration quenching of conventional rhodamine dyes. ABPX series exhibit aggregation-induced emission enhancement (AIEE).
