Gutman–Vidović's maximal-energy conjecture for bicyclic molecular graphs

Let $P_n^{6,6}$ denote the bicyclic molecular graph of order $n$ corresponding to the alpha,beta diphenyl-polyene $C_6H_5(CH)_{n-12}C_6H_5$. Gutman–Vidović's conjecture. For $n=14$ and $n\geq 16$, the bicyclic molecular graph of order $n$ with maximal energy is $P_n^{6,6}$. The source explains that the conjecture was completely solved for bipartite bicyclic graphs, while it remained open for non-bipartite bicyclic graphs at the point discussed.
