Two blue emitters, 3,7-bis(5′-(trifluoromethyl)-1′H-pyrazole-3′-yl)10-ethylphenothiazine and 3,7-bis(5′-(phenyl)-1′H-pyrazole-3′-yl)10-ethyl-phenothiazine and one red, bis-dioxaborine emitter, each based on two, yellow-green emitting, bis-β-diketonate, phenothiazine derivatives, were obtained in high yield and characterized. Systematic investigation of the two-photon absorption characteristics was carried out using one-photon absorption, one-photon excited fluorescence as well as two-photon excited fluorescence spectra. TDDFT computational studies were undertaken to secure an insight into the nature of the compounds' electrochemical and photophysical properties. Low-energy absorption transmissions resemble those observed for the experimental one-photon absorption spectra. © 2009 Elsevier Ltd. All rights reserved.
