Porous organic-inorganic hybrid materials with crystallinity and method for preparing thereof

A porous organic-inorganic hybrid material with crystallinity which has a surface area in the range of 1,500 m2/g to 10,000 m2/g and has a pore volume in the range of 0.1 ml/g to 10 ml/g, wherein the porous organic-inorganic hybrid material with crystallinity is prepared by a method comprising:

• preparing a reaction solution containing a mixture of at least one inorganic metal precursor, at least one organic compound which may act as a ligand, and solvent (step 1);
• and
• forming porous organic-inorganic hybrid materials with crystallinity by reacting the reaction solution (step 2),
• wherein the reaction is conducted under the pressure of about 3 atm or less,
