The Optical Power Limiting Properties of 4Cl1NTP in Solution and Film State

OPL properties of N-heteropentacenes derivatives (4 Cl1 NTP) by Z-scan technique were investigated.Resultsrevealed that the 4 Cl1 NTP showed excellent stability and OPL properties compared with reference sample C₆₀. The 4 Cl1 NTP by modified N and Cl atoms showed higher OPL properties than TP. The NLO performance could be tuned by chemically modified molecular structures, showing that chemical modification could regulate and control the nonlinear optics performance.
