Specialty is the development of new functional material using organic chemistry.Discussions with Reviewers1 Synthesiology and molecular designComment (Hisao Ichijo, Tsukuba Center, Inc.)In Synthesiology, you are required to describe the elemental technologies to realize the research goal, the relationships among the elements, and the process of their integration, to help the succeeding researchers. I think this paper will be valuable to the readers if you follow these points.Comment (Toshimi Shimizu, Nanotechnology, Materials and Manufacturing, AIST)The synthesis of chemical substance is based on diverse utilization and combination of various functional groups, and I believe the trial-and-error in molecular design and synthesis methods is the practice of synthesiology. Therefore, to rearrange the descriptions to fit the synthesis as stated in Synthesiology, I recommend that you discuss the scheme of molecular design that was done for the goal of achieving higher function and simplified synthesis unseen before in conventional gelators. Also, please show a diagram that breaks down the molecular structure of the gelator by elements, show how the elements of conventional gelators were converted in your research, and indicate why the new elements were added to solve which issues in executing the molecular design.Answer (Masaru Yoshida)The point of view of “molecular design and the synthetic approach” = “one form of synthesiology” is very informative. I created diagrams from that perspective and added descriptions to the overall text.2 Outlet as a chemical reagentComment (Toshimi Shimizu)You present the outlet for new practical use i.e. sales as a chemical reagent. If possible, please state the decisions or standards that the chemical or reagent companies use when
