THE PROPOSED PROGRAM RELATES TO THE SYNTHESIS AND EVALUATIONOF FUNCTIONALIZED TETRAAZAANNULENES (TAA) AS O ORGANOMETALLICS CAPABLE OF LITHIUM INTERCALATION.

THE PROPOSED PROGRAM RELATES TO THE SYNTHESIS AND EVALUATIONOF FUNCTIONALIZED TETRAAZAANNULENES (TAA) AS O ORGANOMETALLICS CAPABLE OF LITHIUM INTERCALATION. THE MAJOR OBJECTIVE OF THE PROGRAM IS TO SHOW THAT SUCH FUNCTIONALIZED TAAS CAN TAKE UP LITHIUM IONS REVERSIBLY AND THAT THE POTENTIAL AT WHICH THIS REVERSIBLE REACTION OCCURS CAN BE ALTERED ACCORDING TO THE ELECTRON DENSITY OF PIE-BOND SYSTEM OF THE MOLECULE. THE MAJOR ADVANTAGES OF THE PROGRAM ARE THE HIGH NUMBER OF EQUIVALENTS OF LITHIUM WHICH CAN BE INTERCALATED AND THE POTENTIAL DIFFERENCE WHICHIS AVAILABLE BETWEEN TWO DIFFERENT FUNCTIONALIZED TAAS UPON LITHIUM INTERCALATION. THE TAAS HAVE BEEN CHOSEN BECAUSE TRACER HAS DEMONSTRATED THEM TO BE HIGHLY STABLE ORGANO- METALLICS CAPABLE OF HIGHER LITHIUM INTERCALATION THAN THE PHTHALOCYANINES RECENTLY REPORTED IN JAPAN AS HIGHLY DESIRABLE CATHODE MATERIALS IN SECONDARY LITHIUM BATTERIES. THE PROGRAM APPROACH IS TO PREPARE TWELVE TAAS, EVALUATE THEIR CHEMICAL REACTION WITH N-BUTYL LITHIUM, AND DETERMINE THE ELECTROCHEMICAL REVERSIBILITY AND THE ELECTORDE POTENTIAL OF THIS LITHIATION REACTION.
