A method of making a platinum complex, the method comprising:

• reacting a starting material with n-BuLi using diethyl ether as a first solvent to yield a first intermediate product;
• reacting the first intermediate product with a second solvent to yield a second intermediate product;
• and
• reacting the second intermediate product with a platinum salt in the presence of a third solvent to make the platinum complex, wherein the platinum complex comprises a formula:
• wherein A is selected from:
• an arene, heterocyclic arene, alkyl substituted arene, alkoxy-substituted arene, halogen substituted arene, nitro-substituted arene, cyano-substituted arene, amino-substituted arene, hydroxyl-substituted arene, alkylamino-substituted arene, acyl-substituted arene, alkyl substituted heterocyclic arene, alkoxy-substituted heterocyclic arene, halogen substituted heterocyclic arene, nitro-substituted heterocyclic arene, cyano-substituted heterocyclic arene, amino-substituted heterocyclic arene, hydroxyl-substituted heterocyclic arene, alkylamino-substituted heterocyclic arene or an acyl-substituted heterocyclic arene,
• where x is 1 to 20;
• wherein B is selected from a carbazole, alkyl N-substituted carbazole groups, alkyl substituted carbazole, alkoxy-substituted carbazole, halogen substituted carbazole, nitro-substituted carbazole, cyano-substituted carbazole, amino-substituted carbazole, hydroxyl-substituted carbazole, alkylamino-substituted carbazole, acyl-substituted carbazole, alkyl substituted N-substituted carbazole, alkoxy-substituted N-substituted carbazole, halogen substituted N-substituted carbazole, nitro-substituted N-substituted carbazole, cyano-substituted N-substituted carbazole, amino-substituted N-substituted carbazole, hydroxyl-substituted N-substituted carbazole, alkylamino-substituted N-substituted carbazole and a acyl-substituted N-substituted carbazole group;
