I was wondering if I could express it this way, ‘Not until the leaked information had been publicised did the president make his formal announcement.’

According to the book, I should use “published”, but according to the Longman Dictionary of Contemporary English, “publicise” means “to give information about something to the public, so that they know about it”.

Do you think that this usage of "publicise" is appropriate in my sentence?

Thank you in advance.

No, "after the publication of the leaked information" means "after the leaked information was published" (not publicised).

"To publish" and "to publicise" mean different things.

Publicise is not just making something available (publish) but also involves promoting it so that people know (advertising, for example).
