    • Curcuma aromatica essential oil is blue-black dark liquid with camphoraceous, woody, amber and spicy characteristic odour and is less valued in market, however the prepared value added products have very good shining color with the improved fragrance. The present invention relates to an efficient process for the modification of Curcuma aromatica essential oil to develop value added fragranced products, the process comprising the steps of mixing of essential oil with one solvent or a combination of more than one solvents, cooling the mixture over ice bath or at lower temperature at rotation of 1000 rpm or at simple magnetic stirrer at high speed, addition of reducing agent at different proportion at a certain time period for desired product, after completion of the reaction, addition of ice water to the reaction mixture to terminate the reaction, extracting the mixture using solvent for three to five times, washing the extractive with dilute acidic water and then with water, washed product was dried at lower temperature to obtain modified essential oils in order to develop fragranced products with recovery of 60 to 95% and use of the modified essential oil in the range between 0.05 to 100% in perfumery or allied industries.

    • 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 Zn 2+ specific probe for detecting Zn 2+ in cellular environments. Assay with formula 3 is used as a fluorescent probe for two photon imaging of Zn 2+ ions in HeLa cells. The high two photon absorption cross section and fluorescence quantum yield of formula 3 made it as a useful probe for detecting Zn 2+ in cellular environment by two photon excited fluorescence imaging.
    • 本发明是提供可用于固态照明的式1和2的高度固体发射荧光团。 公式1和2分别在蓝色和绿色区域具有良好的固态发射。 式1A和2A的锌络合物在固态下分别具有黄色和红色发射。 本发明还提供式1和2的高固态发射测定法,通过在365nm发射固态LED上涂覆颜色可调谐材料将UV光转换成可见光。 本发明还提供了用于在溶液中用不同的抗衡离子筛选金属盐的咔唑封端的联吡啶。 可以通过注意溶液中的荧光变化来监测各种金属盐的区别。 具有不同抗衡离子的锌盐在溶液中具有不同的发射颜色。 本发明还开发了用于在细胞环境中检测Zn 2+的新型双光子活性荧光Zn 2+特异性探针。 使用式3的测定用作HeLa细胞中Zn 2+离子的双光子成像的荧光探针。 式3的高双光子吸收截面和荧光量子产率使其成为通过两个光子激发荧光成像在细胞环境中检测Zn 2+的有用探针。
