( E )‐3‐(10‐ethylphenothiazine‐3‐yl)acrylic acid (LCOOH) was synthesized. LCOOH reacted with Ph 3 Sn(OH) and n Bu 2 SnO to afford Ph 3 SnO 2 CL ( 1 ) and {[nBu 2 SnO 2 CL] 2 O} 2 ( 2 ), respectively. The structures of all the compounds were solved by single‐crystal X‐ray diffraction. Compounds 1 and 2 present discrete and ladder frameworks, respectively. The one‐photon absorption and excited fluorescence, and two‐photon excited fluorescence spectra of all the compounds were systematically investigated. The results show that the two organostannoxanes exhibit much more enhanced two‐photon absorption properties than LCOOH. TDDFT computational studies have been performed to elucidate the electronic structures of the ground state of LCOOH.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
