TL;DR: In this article, the development of organic materials with large (2) nonlinearity are discussed, such as molecularengineering of large hyperpolarizability, which can be useful for frequency conversion of lasers and electro-optic modulation of optical radiation.

Preparation and Crystal Structures of 4-(4′-Pyridylthio)-1-methylpyridinium Salts: Assembly of a Donor–Acceptor-Type Molecule Containing a Sulfide Bridge
TL;DR: A series of ionic 4-(4′-pyridylthio)-1-methyl pyridinium salts with different counteranions (1, I−; 2, BF−4; 3, PF−6; and 4, OTf−, where OTf=trifluoromethanesulfonate) have been prepared as discussed by the authors.

Organic Materials for Nonlinear Optics
TL;DR: In this paper, the authors investigated the nonlinear optical properties of certain organic and polymeric materials and showed that these materials possess the largest observed optical nonlinearities and are suitable for waveguiding and integration.

A theoretical treatment of the structural aspects of the topochemical polymerization of diacetylenes
TL;DR: In this article, a theoretical model for predicting which diacetylene monomers will undergo topochemical polymerization has been developed and the semi-empirical SCF-MO methods MNDO, AMI, and PM3 have been used to carry out calculations based on this model.
