Abstract:	摘要： Two analogous multipolar chromophores (1 and 2) that contained 2,3,8‐trisubstituted indenoquinoxaline moieties have been synthesized and characterized for their two‐photon absorption properties, both in the femtosecond and nanosecond time regimes. We demonstrated that their multi‐branched framework structures, which incorporated appropriately functionalized indenoquinoxaline units, afforded large molecular nonlinear absorptivities within the studied spectroscopic range. Effective optical‐power‐limiting and stabilization behaviors in the nanosecond regime of dye molecule (2) were also investigated and the results indicated that such a structural motif could be a useful approach to the molecular design of highly active two‐photon systems for quick‐response and related broadband optical‐suppressing applications, in particular for confronting laser pulses of a long duration. In pole position: Two multipolar chromophores that were derived from 2,3,8‐functionalized indenoquinoxaline units manifest strong and wide dispersed two‐photon absorption (2PA) in the NIR region under the irradiation of femtosecond laser pulses. Moreover, these model fluorophores could act as effective power‐limiters/stabilizers against nanosecond laser pulses within the same spectroscopic regime. 其他題名： Chem.
