Enhanced two-photon absorption of novel four-branched chromophore via vibronic coupling

A novel four-branched chromophore TOZ-4 with starburst linker was synthesized and showed two-photon absorption cross-section (δ) as large as 5254 GM, which was principally resulted from vibronic coupling enhancement.
