title: Trivalent boron as acceptor in D-pi-A chromophores: synthesis, structure and fluorescence following single- and two-photon excitation.
abstract: A series of new donor-pi-acceptor type compounds with trivalent boron as acceptor which show strong two-photon excited up-conversion fluorescence have been synthesized and one crystal structure described.
