*total-coloring*of a graph is a coloring of the edge set and vertex set. A path in a total-colored graph is a

*total proper path*if the coloring of the edges and internal vertices is proper, that is, any two adjacent or incident elements of edges and internal vertices on the path differ in color. For a connected graph

*G*is

*conflict-free connected*if every two of its vertices are connected by a path, which contains a color used on exactly one of its edges. The

*conflict-free connection number*of a connected graph

*G*, denoted by

**Front Cover**: In article number 1700871, Jianbo Tan, Li Zhang, and co‐workers describe a novel enzyme‐catalysis‐induced reversible addition‐fragmentation chain transfer (RAFT)‐mediated dispersion polymerization for preparing AB diblock copolymer nano‐objects with complex morphologies, performed at room temperature. Taking advantage of the oxygen‐tolerant feature of enzyme cascade catalysis, block copolymer...
