Patent ID: 7932213

Claim:
An array comprising: a plurality of more than one type of organic small molecule, having a molecular weight of less than 1500 g/mol, attached to a solid support through a benzylidene linker, wherein said solid support is a substantially flat surface derivatized with diazobenzylidene moieties, whereby said organic small molecules become attached to said support through reaction with said diazobenzylidene moieties, wherein attachment of said organic small molecules to said support is robust enough so that the small molecules are not inadvertently cleaved during subsequent assaying steps, wherein the density of said array of organic small molecules comprises at least 1000 spots per cm 2 , and wherein said organic small molecules attached to said benzylidine linker attached to said solid support is as shown below: wherein X is a heteroatom selected from the group consisting of O, S, and N, of the attached organic small molecule R.
