Controlled self-assembly of Triazatruxene overlength microwires for optical waveguide

Abstract Controlled low-dimensional organic nanomaterials have great application prospects in the field of optoelectronics. However, it is difficult to obtain the controlled synthesis method for organic microstructure, because the interaction of the organic molecules is easy to be affected by the external environment. In this paper, we reported that the ultra-long microwires of the ethyl modified soft@rigid 2D Triazatruxene core with large planar π configuration were prepared by external environment. During the optical waveguide process, this prepared microwires displayed low propagation loss with 0.0632 dB/μm at 425 nm, which is lower than most of organic aggregations. This microstructure preparation method will provide beneficial enlightenment for the development of miniaturized devices of photonic integrated circuits.
