Paper Abstract

Here we study self-assembled of 9-diethylamino-5-benzo[α]phenoxazinone 9 . AFM, SEM, Raman imaging, studies demonstrate that such materials form micron-sized tub-like structures with rectangular shape. These microstructures show both active and passive wave guiding modes. Applying wavelengths in resonance 532 nm, and in non-resonance (785nm) with the molecular electronic absorption bands was undertaken for active and passive wave guiding studies. PL spectra capping point, the body and emerging light points were investigated. Meanwhile, Raman scattered photons were also acquired which maintain the polarized light propagation direction(s) and its interaction with tube molecules. The hollow features and tubes defect were identified using Raman imaging. These studies showing that excellent wave guiding features are present using these self-assembled micron-tube structures.
