The test with MOFs is their mechanical dependability. The materials are defenseless against physical and substance stress, which can influence their structure and, eventually, their exhibition. Since numerous MOF applications include cycling between various temperatures, changing weights, and other compound atoms applying hair-like powers, it has gotten
central to the field that MOFs highlight adequate mechanical security. Presently, the lab of Berend Smit at EPFL Sion with Lev Sarkisov of the University of Edinburgh have found how the mechanical properties of MOFs identify with their structure, which has for quite some time been a deterrent in improving the steadiness of the materials.

'Carbon has an exceptionally uncommon status in the occasional table of the components and structures the reason for all types of life because of the incredibly huge number of synthetic mixes it can frame,' clarifies Prof. Dr. Dirk M. Guldi at the Chair of Physical Chemistry I at FAU. 'The most notable models are three-dimensional graphite and jewel. Notwithstanding, twodimensional graphene, one-dimensional nanotubes and zero-dimensional nanodots likewise open up new open doors for gadgets applications later
on.'

Materials comprising of inorganic and natural segments can join the best of two universes: in specific situations, the alleged MOFs - short for metalnatural systems - are organized in similar request as precious stones and are simultaneously permeable and deformable. This opens up the possibility of clever materials for energy-sparing specialized applications. Nonetheless, so far a couple of adaptable MOFs have been recognized. An examination group from Ruhr-Universität Bochum (RUB) and Technical University of Munich (TUM) has utilized tests and recreations to discover by what implies MOFs can be delivered adaptable and why: they deceived the situation by utilizing sharp synthetic controls to empower an assortment of vigorously comparative plans in the translucent request.

In the present work we synthesized some new compounds of Design and Synthesis of Some New Derivatives of 6,7-Dicholorophthalazine 1,4-(2H, 3H) dione via the reaction of
4,5-Dicholoro phthalicanhydride with hydrazine hydrate resulted 6,7-dicholorophthalazine 1,4-(2H, 3H) dione (I). The compound (I) reacted with alcoholic potassium hydroxide to obtain the potassium salt of 6,7- Dicholorophthalazine 1,4-(2H, 3H) dione (II). Also the acetanilide derivatives (III) condensed with compound (II) in dimethylformamide (DMF) on water bath for six hours, gave compounds (IV 1-12) which choose some of them to test as anti-convulsant activity compared with phenobarbitone sodium as standard reference drug. The choice new compounds which tested revealed anti-convulsant activity.

We prepared phthalazine -1,4 (2H, 3H) dione (1) from phthalic anhydride and hydrazine hydrate. The compound (1) reacted with alcoholic potassium hydroxide, we obtained on
compound (2) (the potassium salt of phthalazine -1,4 (2H, 3H) dione. Also we synthesized acetanilide derivatives (3) from aniline derivatives with chloroacetyl chloride. Then we reacted the compound (2) with the compounds (3) resulted compounds (4a-q) which tested some of them (some new compounds acetanilides) against phenobarbitone as standard reference drug as anticonvulsant agents, some of these new compounds revealed promising anticonvulsant activity.
