The Mulliken analysis of platinum-doped graphene under varying external pressures (0, 0.1333, 0.26667, and 0.4 Pa) reveals significant variations in the electrophilic character of the platinum atom and its influence on neighboring carbon atoms (C2, C6, and C8). At these pressures, the platinum atom exhibits electrophilic character values of 0.176, 0.279, 0.274, and 0.176, respectively, indicating a pressure-dependent fluctuation in its ability to accept electron density. These induced charges are distributed across the nearby carbon atoms, with C2 showing values of 0.185, 0.176, 0.177, and 0.185, C6 with 0.231, 0.164, 0.165, and 0.231, and C8 mirroring C2 with 0.185, 0.176, 0.177, and 0.185. The variation in charge distribution suggests that external pressure modulates the nucleophilic and electrophilic interplay within the system, altering the reactivity and adsorption properties of the doped graphene. The pronounced charge on C6 at zero and maximum pressures highlights specific nucleophilic enhancements at these conditions, which could affect interaction with electron-deficient species .
