Structural, optical, thermal, mechanical, dielectric and laser damage threshold studies of a succinate salt of creatinine for nonlinear optical applications

•The chemical compositions of creatininium succinate (CS) were confirmed by NMR (1H and 13C) technique.•Interestingly, the material exhibits large laser damage threshold up to 5.2 GW/cm2 and higher thermal stability of 245 °C.•CS is a one of the low dielectric constant material with lesser defects.

In this work, the structural, optical, mechanical, dielectric, thermal and laser-induced damage threshold (LDT) studies of a promising organic NLO material creatininium succinate (CS) were reported. CS exhibits admirable properties such as good thermal stability (247 °C), low dielectric constant (εr=8.5) at higher frequencies and higher LDT up to 5.24 GW/cm2 (3.5 times greater than urea) which favor this material most suitable for advanced laser applications.
