The present invention relates to novel donor-acceptor fluorene compounds, which can be used as for the fabrication of electroluminescent devices, and a process of preparing said novel compounds. More particularly, the present invention relates to amine donor and nitrile/ester acceptor fluorenes, fluorenones their &#x3c0;-conjugated systems and related compounds, processes for preparing the said compounds including oxidation of fluorenes to corresponding fluorenones and their use in preparing organic electronic devices such as organic light emitting diodes (OLEDs), photovoltaic/solar cell, Field effect transistors and other useful electroluminescent devices. The compounds are prepared by reacting 2H-pyran-2-ones in isolated or rigid conformations with cyclic ketones containing methylene carbonyl moiety in the presence of a base in an organic solvent. The present invention also relates to a new concept and approach to overcome the problem of 'Green emission defect' in 9-unsubstituted fluorene-based organic light emitting diodes which occurs due to the conversion of fluorenes to fluorenones that show emission mainly in green-yellow region. In the present invention we have placed donor-acceptor substituents in such a way that donor-acceptor fluorenones show emission in the blue region (instead of green-yellow region) thus improving the blue color purity and overcoming the problem of green emission defect.

Donor-acceptor fluorene scaffolds: a process and uses thereof

The present invention relates to system for calibrating plurality of pressure transducers, said system comprising plurality of pressure transducers (to.n) mounted on a mounting means () which receives pressure input from a pressure source () via a hollow pipe () and distributes the pressure evenly to all the pressure transducers, said plurality of pressure transducers are mounted on the mounting means and placed inside a vessel () as to vary the temperature of the pressure transducers, said pressure source is also connected to a standard pressure transducer () whose temperature is maintained at the same level as that of pressure transducers (to.n).

The present invention relates to a pressure housing for in-water pressure based systems and to a method for improving the life of the transducers and electronics of underwater systems by maintaining a humidity-free and clean environment around them by avoiding the entry of humidity, dust, or any suspended particles in the air during occasional data offloading and battery replacement in a humid and dust-laden field station; improving the ease of closing and opening of the pressure housing by the use of a novel arrangement thereby avoiding the use of conventionally employed cumbersome protruding and corrosion-prone locking devices such as screws, bolts, or clamps; and implementing reliable transmission of water pressure to the pressure port of the transducer, simultaneously minimizing the errors arising from dynamic pressure effects, preventing its chemical corrosion from saline water, and arresting bio-fouling in the vicinity of the pressure inlet.
