Abstract: A method for manufacturing a modified porous organic framework includes steps as follows. A mixed solution is provided. The mixed solution includes a porous organic framework, a plurality of group donors and a solvent. The porous organic framework includes a plurality of first ligands. Each of the first ligands includes at least one tetrazine group. Each of the group donors includes a reactive group and a modifying group covalently connected with each other. The reactive groups are alkenyl groups, alkynyl groups, aldehyde groups, ketone groups or a combination thereof. A modifying step is conducted, wherein at least one of the reactive groups of the group donors is reacted with at least one of the tetrazine groups of the first ligands, so that at least one of the modifying groups of the group donors is covalently connected with the porous organic framework, whereby the modified porous organic framework is obtained.

Abstract: An organic electroluminescent material is shown in the following general formula (1), {[M(L)(H2O)x].(H2O)y}n??General Formula (1) wherein x is between 1 and 4, y is between 1 and 8, and n is a positive integer. M is any one selected from the group consisting of beryllium (Be), strontium (Sr), and radium (Ra). L is an organic ligand containing a naphthalene group and an anhydride group. M and L form metal-organic frameworks. An organic electroluminescent device containing the organic electroluminescent material is also disclosed.
