Self-Assembly of Discrete Multi-Chromophoric Systems.

Self-assembly of chromophoric systems is a prerequisite to create well-ordered, processable nanomaterials with multiple functionalities. In the past two decades, the field of functional organic materials has primarily focused on systems featuring only one type of dye/π-conjugated unit. Consequently, many reports with mechanistic insights on the self-assembly of the dyes featuring different molecular packing have been reported.

Development of starch based intelligent films by incorporating anthocyanins of butterfly pea flower and TiO and their applicability as freshness sensors for prawns during storage.

Intelligent pH sensitive starch films were developed by incorporation of anthocyanin pigment extracted from butterfly pea flower (BPE) and nanosized TiO using the method of solution casting. This research work evaluated the influence of BPE and TiO on the physical and structural properties of starch films. The physical properties of the starch films could be significantly altered by the addition of BPE and or TiO.
