Abstract: The present invention relates to design and applications of a class of water-soluble small molecules represented by Formula 1. In aqueous solutions the said molecules exhibit lower critical solution temperature (LCST) phase transition near room temperature, imparting a temperature triggered switching of transparency stages. Further, it discloses a solution comprising Formula 1 and a scalable smart radiative energy management system that takes form of a dynamic window, wherein the aqueous solution is sandwiched between two transparent glass panes to enable modulation of light and heat transmission. With simple and economical starting materials, the dynamic windows of present invention represent leaps towards creating a niche technology with multifarious applications in developing scalable, smart energy management systems for indoor building environments.

Abstract: Liquid electrolytes in electrochemical devices suffer from leakage issues and hence gel or solid electrolytes are generally preferred. The present invention intends to disclose the development of a gel electrolyte system which differs from conventional gel electrolytes via the addition of a composition controlled molecular additive, and its use in laminated electrochromic devices with improved performance.

Abstract: The present invention is to provide highly solid state emissive fluorophores of the formula 1 and 2 useful for the solid state lighting. The formula 1 and 2 have good solid state emission in blue and green region respectively. The zinc complexes of formula 1A and 2A have yellow and red emission respectively in solid state. The present invention also provide high solid state emissive assay of formula 1 and 2 to convert UV light into visible light by coating the color tunable materials on the 365-nm emitting solid state LED. The present invention further provides carbazole end-capped bipyridine for screening of metal salts with different counterions in solutions. The discrimination of the various metal salts can be monitored by noting the fluorescence change in solution. The zinc salts with different counterions have different emission color in solution. The present invention also develop a new two photon active fluorescent Zn2+ specific probe for detecting Zn2+ in cellular environments.

Abstract: The present invention describes the use of a fluorescent NIR dye for various applications by simply changing the solvent conditions. Molecule of formula 1 in the monomeric state (30% ACN/25 mM phosphate buffer) can be used for the sensitive detection of thiols and monitoring minor fluctuations in the thiol concentration inside live cells. Molecule 1 in the self-assembled state (25 mM phosphate buffer) can be used for labeling of serum albumin protein either covalently or noncovalently at specific pH. The probe 1 specifically bind with the serum albumin proteins noncovalently at lower pH gives a “turn-on” NIR emission whereas it binds covalently at higher pH gives a “turn-on” green fluorescence. Since the probe detects serum albumin proteins selectively in presence of other thiol containing small molecules, the probe can be used as an excellent sensor for serum albumin proteins. The dye-protein complex of various ratios can be used as sensors to detect the pH variations in a broad window from 4.6-11.

Abstract: The present invention provides a novel fluorescent molecule having formula 1 which exhibit emission color change when in contact with moisture useful for the preparation of fluorescent paper, allowing self-erasable writing, security label for document authenticity, check and prevention of currency counterfeit. Compound of formula 1 when coated on paper results in blue emitting surfaces on which writing is possible using water as ink. The images undergo self-erasal after 6 hours making the paper reusable or instantly with hot air. The images are visible only on illumination with a UV lamp having wavelength 365 nm. The material can be coated on any document to create security label which changes color on touching with a wet surface or water pen and will go back to the native color when the moisture is dried off after a time frame. This strategy is used to create a security label for currency bills for checking original and fake currency notes or any other documents for authenticity.
