Key Points

The aim is to synthesize and examine the nonlinear optical properties of a new polar ionic cocrystal.
Synthesis of 2,4-diamino-6-methyl-1,3,5-triazinium phenylphosphinate monohydrate.
Characterization of nonlinear optical properties such as second-harmonic generation and birefringence.
The cocrystal exhibits a second-harmonic generation response approximately 2.0 times that of a conventional reference material.
High birefringence values were noted, indicating potential for enhanced optical performance.

Implication

Synthesis of a polar ionic cocrystal reveals strong second-harmonic generation in optical applications.

Abstract

A polar ionic cocrystal, 2,4-diamino-6-methyl-1,3,5-triazinium phenylphosphinate monohydrate (AMTPP), (C4H8N5)(PhPHO2)‧H2O, was successfully synthesized. The material exhibits exceptional nonlinear optical (NLO) properties, including a secondharmonic generation (SHG) response approximately 2.0 times that...
