Exclude a specific string by regular expression

Hello,

I'm trying to get familiar with the Regular Expression on Property Definition Editor. I saw that it is possible to exclude a list of characters through the syntax [^abcd]*
This way if I write any string that contains one or more of these characters I get an error. for example I have an error for each of these strings: "1a" "efa" "ab" "ca" "abcd" etc ..
Is it possible to exclude a specific string? I would like all characters to be allowed except the "abcd" string. In this case the examples above would all be ok except the last one. I would like to receive error only if I write exactly the string "abcd"

 

thank
