Topotactic Reactions in Organic Crystals.

Crystalline organic compounds have been observed to react in a number of cases in a manner which suggests that the process is dependent on the geometry of the disposition of reactive groups in the crystal lattice. Such a process, first observed with inorganic reactions, has been designated by Kohlschuetter' as "topochemical," and several criteria may be used to show that a reaction falls into t...

Flexible ferroelectric organic crystals

Flexible organic materials possessing useful electrical properties, such as ferroelectricity, are of crucial importance in the engineering of electronic devices. Up until now, however, only ferroelectric polymers have intrinsically met this flexibility requirement, leaving small-molecule organic ferroelectrics with room for improvement. Since both flexibility and ferroelectricity are rare prope...

Semi Organic Nlo Crystals

The present fascinating field of research is to synthesize, grow and characterize semi organic NLO crystals. Here an attempt has been made to synthesize and grow number of NLO semi organic crystals. The semi organic crystals posses both the good qualities of host organic material and additive-inorganic material. The crystals grown are amino acidγ-Glycine with additives namely, Potassium Nitrate...

Amphiphillic organic crystals.

The amphiphillic character, that is, the capacity to simultaneously attract and repel water, has been traditionally reserved to organic molecules such as phospholipids and surfactants, containing both hydrophilic and hydrophobic groups within the same molecule. However, this general concept can be extended to artificial structures such as micrometer-sized particles, the so-called Janus particle...
